Anolon® Cookware Giveaway

But before you get distracted by the prospect of prizes galore, let’s talk onions.

Or, more specifically, onion jam.

It’s unlike any jam you’ve had before. Rich and savory, with a hint of sweetness and verdant rosemary, this jam would make an excellent side on your holiday table. Serve it with biscuits or toast; spread it on your turkey, swirl in in your mashed potatoes. It’s a versatile spread that’s part condiment, part sauce, and entirely delicious.

Balsamic Rosemary Onion Jam

You know what’s amazing? Goat cheese biscuits with onion jam, that’s what. *Drops mic*

Balsamic Rosemary Onion Jam

What starts as almost 10 cups of sliced onions cooks down to a sweet, sticky jam. It may seem like a measly amount for all that time and effort, but that’s before you taste just how much flavor is packed into each bite.

Balsamic Rosemary Onion Jam

Yield: 3/4 cup

Total Time: 1 hour


  • 2 tablespoons olive oil

  • 4 large onions, thinly sliced (about 10 cups sliced)

  • 3 tablespoons balsamic vinegar

  • 2 tablespoons brown sugar

  • 1 1/2 teaspoons finely chopped fresh rosemary or 1/2 teaspoon dried rosemary

  • 1/4 teaspoon kosher salt

  • 1/4 teaspoon freshly ground black pepper


Preheat oil in a large skillet over medium heat. Add onions. Cook, stirring occasionally, until onions are soft, translucent, and just beginning to brown, about 20 minutes. Stir in balsamic vinegar, brown sugar, rosemary, and salt and pepper. Continue to cook, stirring occasionally, until liquid is evaporated and onions are dark brown and reduced to 3/4 cup, about 40 minutes more. Remove from heat and let cool. Store in a glass jar or airtight container in the refrigerator for up to 1 week.

  1. I follow both Love & Olive Oil and Anolon® on Pinterest as Margot Core.

  2. I would add minced fennel bulb to the recipe and as it cools I would incorporate an ounce each of whiskey and honey. This would give the jam depth of flavor and expand it’s overall use. 

  3. I would put some leeks in there as well!

  4. Oh man, I could add some honey to the mix

  5. Let’s see…. I think I would add some cherry tomatos. Potentially add feta upon serving!

  6. I get love&olive oil emails!

  7. I would put this into a caprese to give it a bunch of flavor with the onions.

  8. I might use it in a dip, but it looks delicious the way it is!

  9. I would love to add some fig to it!

  10. I subscribe

  11. I’d add a hit of heat to the jam – a little red pepper flake or chili. 

  12. After tasting how sweet it is, I would put on a cheese platter. With some crusty bread or crackers, apples and pears… Mmmmm. Already feels like a party!

  13. I would use sweet onions and Vom Fass Medeno Balsamic Vinegar (to die for!). In fact, that’s what I’m planning on doing. Since I make a killer Southern buttermilk biscuit, that’s my plan!

  14. I would add a little spice, some red pepper perhaps or add a little orange zest.  Looks yummy, can’t wait to try it.

  15. I would serve this with a juicy pork tenderloin and mashed potatoes

  17. This recipe sounds so good I think I’d use it as it is. Maybe it’d be good on eggs in the morning? Or with a bagel and cream cheese.

  18. This looks so good! We are all onion fanatics at my house. First, I would make a double batch. The slicing goes quickly with a mandolin slicer. ;)

    I think I’d like to try it with thyme either instead of the rosemary, or perhaps a blend of the two. And since thyme is a more delicate herb – I’d wait until about halfway through the cooking to add it.

  19. I’m already subscribed! yay! Debra (dot) womack (at) gmail (dot) com

  23. For updates, I’d definitely add some red wine in the mix. And I might do a spicier version with red pepper flake in it—just a pinch! I live in Walla Walla, so undoubtedly I’d use our Walla Walla Sweets for an extra sweet punch, the spice would cut that just right!

  24. Love this onion jam, Lindsay! It would make such a delicious, unique holiday gift.

  25. This looks good served on a crostini or maybe as a condiment on a burger. Love your recipes!

  41. What a delicious recipe! 
    I would slice figs in half, add a large dollop of this jam and wrap it in proccuito carmalizing it all in the oven. Would make a sinfully delicious appetizer to serve.

  42. Onion jam my own way…. I told my hubby about onion jam and he said “eww” too quickly bc I’m dreaming up some added mango and ginger and finally figuring out how to make those delicious Indian chutneys. Perhaps w some apples instead of mango since they’ll be still in season. :-)

    I subscribe to the email already and would love, hug, and squeeze that Anolon set with cooking adventures. Pick me!

  43. I would pan fry large rounds of potato and serve them with a dollop of this jam and some creme fraiche for a delicious appetizer!

  50. yum! I think that I´d try your recipe first before trying out any modifications, although I would probably use hazelnut oil instead of olive oil.

  51. I’m thinking it would be fabulous in a grilled cheese.  UMMM

  58. I’d use Vidalia Sweet Onions. I live in Georgia and they’re a staple around here. Also, I think I’d experiment with different balsamic vinegar flavors. Fig, perhaps? Maybe a selection of berries? This sounds really yummy!

I love it on almost anything; flatbread with arugula and goat cheese, in a fritatta, on a burger or grilled cheese, on top of fried green tomatoes with bacon and spicy black beans…the list goes on and on.

  63. I follow on Pinterest –   ancadaniela

  64. I’d stuff it in puff pastry with cheese!

  72. Subscribed to your newsletter.

  73. I would serve this on a pork loin sandwich.

  95. Onion jam with beets and feta!
    Grilled cheese w/ onion jam!
    Spinach and onion jam omelet!

  96. I would smear it on a delicious biscuit with fresh crumbled goat cheese! And maybe add some bacon. Bacon AND onion jam? Yum!

  97. Oooh this sounds delish as is, but I’m sure my roommates would want to kick it up a notch with some chili powder!!

  98. I’d put it on a buttered bagel and sausage sandwich.
